Blazer gas tank in C10??
I need a new gas tank for my LSx swap on a 1985 C/10 SWB. I can get this 1990 blazer tank. Is this a direct bolt-in on the pickup chassis? I know the fuel inlet will need to be relocated, but I can get it for nothing.
Anyone know how many gallons the blazer tank is.

If I remember right my 82 blazer had a 25 gallon tank on it..I think they had a 30 gallon also...I would need a big ladder to put gas in that one..ha ha

Re: Blazer gas tank in C10??
I don't know if it will "bolt in"..if your tank is good I would consider keeping it and running external pump...that's what I did on mine and I've had no problems...

Re: Blazer gas tank in C10??
The only difference between the 1987 tank and the earlier ones is a small pan welded to the bottom inside. Must be a baffle but the donar truck I used for the LS motor didn't have any baffle inside its plastic tank.

Re: Blazer gas tank in C10??
Your donor truck didn't have baffles in the tank because they use a fuel bucket type sender. The bucket keeps fuel at the pump at all times. You really need some kind of baffle in a tank with an in tank mounted pump if it doesn't use the bucket type sender. For the price of a new '87 tank, around 80 bucks new, I would go that route before trying to adapt a blazer tank that you don't know what the inside looks like. Some things are not a good deal even if they are free.

I wish the donor fuel sending unit with pump would work in my '85 tank. That would be nice.

Re: Blazer gas tank in C10??
For the price, I just bought a new 87 pickup tank and sender, the EP381 pump drops right into the sender and plugs into the harness. Like a glove.

You need the sending unit from an 87' and an ACDelco EP381 pump (which fits directly into the 87' sending unit as mentioned by MalibuSS). I used a Walbro pump instead of the EP381, but the concept is the same: Here is the baffle in the 87' tank: Fully assembled: |

Re: Blazer gas tank in C10??
Did you have to cut the frame anywhere for it to fit ?

Re: Blazer gas tank in C10??
Yes, there was a lot of frame trimming. 1/4 inch to 1 inch in some places

Re: Blazer gas tank in C10??
Hello to all. LS1nova71 is correct. trust his expertise. He would know. The cheap option is for you, I think, is to use the stock, in-cab tank, with a external fuel pump. you can also modify the stock, in-cab tank and regulator, and use an internal fuel pump. To make the in-cab tank work, I modified the stock, Fuel sending unit with a feed and return, with AN fittings, while using an external fuel pump. My buddies hate in cab tanks so I eventually removed the in-cab tank, bought a fuel cell, and installed the fuel cell behind bridge, for my air bag suspension. good luck. Clark.

Re: Blazer gas tank in C10??
This is the best idea for an In-cab fuel tank. Check out Dayj1. He has a great thread "Another way to skin the cat; the High Torque 292 LS swap",
with some useful ideas. check it out. |
